Expressing concern over Kerala Cabinet's decision to build a new dam downstream the Mullaperiyar dam and Andhra Pradesh Government's decision to construct a check dam across river Palar, the PMK leader said the DMK Government should immediately convene an all-party meeting to elicit the views of party leaders and initiate further action.

He said the Tamil Nadu Government should approach the Supreme Court to restrain both the Kerala and Andhra Pradesh governments from proceeding with the construction of the dams, which was against the interests of Tamil Nadu.

He said after the Supreme Court allowed the water level in the Mullaperiyar dam to be raised to 142 ft, the Kerala Government brought out amendments to its Irrigation and Water Conservation Act with a view to thwart the implementation of the apex court order.

When the suit filed by the Tamil Nadu Government against the amendments was pending before the Supreme Court, the Kerala Government had unilaterally decided to build a new dam, which amounted to contempt of court, Dr Ramadoss contended.

The Tamil Nadu Government should immediately file a contempt of court case against Kerala Government in the apex court and obtain a stay order, after ensuring that the petition was taken up for hearing at the earliest.

Besides the legal action, Chief Minister M Karunanidhi should bring it to the notice of the Centre, especially Prime Minister Manmohan Singh, the Kerala Government's ''unilateral action,'' which posed a threat to the ''federal set up'' and jeopordaised the cordial relations between the two states.

The DMK Government should also move the Supreme Court to stop the Andhra Pradesh Government from constructing the check dam across river Palar, which would be detrimental to the interests of people of atleast five northern districts of Tamil Nadu, he said.
